The City of Glendale Traffic Count Program provides traffic counts, contingent on funding, annually. The data collected is represented in Average Daily Traffic (ADT) volumes throughout the City of Glendale.

ADT is defined as the total volume of traffic passing a point or segment of a roadway facility in both directions for one year divided by the number of days in the year. The City of Glendale provides the most recent ADT for a roadway segment, which is reflected as Current ADT.

The City of Glendale utilizes ADT as a traffic management tool to incorporate intersection safety improvements where traffic volumes warrant a change.
